After analyzing the performance of the coherent tree - structured optimal joint detection ( tsojd ) for qpsk signals and deriving a non - coherent multi - user weight / phase estimator, the dissertation proposes a low complexity non - coherent multi - user weight / phase optimal joint detection algorithm. besides, the dissertation proposes a partial coherent multi - user / iv weight / phase optimal joint detection algorithm and some useful conclusions are obtained in comparison experiments. 4. in the research on the diversity techniques for fast fading multi - path channels, the dissertation proposes a time - scale rake receiver, and analyzes its performance with the conception of auto - wavelet - transform ( awt ) and time - - scale resolution
提出了過飽和低復雜度qpsk信號的樹型最佳聯合檢測演算法，並分析了相應最佳接收機的性能及相位偏差對性能的影響等問題；考慮了載波相位和多用戶信碼的聯合檢測問題，通過理論推導給出了過飽和多址系統中多用戶信碼/相位聯合估計子，提出了低復雜度非相干多用戶信碼/相位最佳聯合檢測演算法，並分析了此非相干最佳接收機的誤碼性能及相位提取誤差等有關問題；提出了部分相干多用戶信碼/相位最佳聯合檢測演算法，通過計算機模擬分析了該接收機的誤碼性能及相位提取誤差等有關問題，並與相干、非相干解調兩種情況作了比較，得出了一些有益的結論。
